“…[ 29,30 ] In order to improve the interaction between the inorganic filler and PVC matrix, surface modification by oleic acid was applied on MH to increase its hydrophobic property, leading to enhanced flame retardancy of PVC composite compared with that of the one containing the unmodified magnesium hydroxide. [ 35 ] The LOI value of PVC containing modified MH showed a decreasing trend after an initial increase and the highest value of 33.8% was obtained when the filler reached 30 phr. Another flame retardant, zinc hydroxystannate (ZHS), was also exploited to coat on the surface of hydroxides in order to improve the flame retardant efficiency.…”

As a versatile star product, poly(vinyl chloride) (PVC) has kept active in our daily life all through since it was invented. However, the severe fire hazard and heavy smoke produced during combustion, particularly the extensively used flexible PVC products, have been puzzling manufacturers and researchers for ages. Over the last decade, multifarious flame retardants and smoke suppressants were developed for PVC materials. In this review, combined literature with the results based on the research from our group, recent emerged flame retardants and smoke suppressants for PVC are introduced. Meanwhile, the flame retardant mechanisms and experimental analysis results are described to understand the relationship between characters of flame retardants (including chemical compositions, structures or morphologies) and fire performance of the composites. The potential substitutes for traditional harmful flame retardant antimony trioxide are discussed aiming to the emphasis on increasing prominent environmental concerns. In particular, one section is dedicated to new approaches for the preparation of novel environmentally friendly and high-efficiency flame retardants. It is hoped that this review will not only summarize the new emerged flame retardants and smoke suppressants for PVC, but also provide the new trend to prompt sequent exploration in both academic research and industrial application.

“…Therefore, good dispersibility and stable interfacial adhesion strength between MH and the polymer matrix are needed for MH to execute an excellent ller function. 23 To solve this problem effectively, most researchers have focused on the modication of MH by using silane coupling agents, 18,24,25 saturated or unsaturated high fatty acid salts, 23,26,27 titanate coupling agents 28,29 and other modiers. 24,29 The introduction of these modiers improves the dispersion of MH to varying degrees, but it is accompanied with new process costs and environmental problems.…”

“…Polyvinyl chloride (PVC) is one of the most commonly used thermoplastics and is widely applied in the fields of furniture, building materials, textiles, and transportation due to excellent mechanical properties, good chemical resistance, superior electrical insulation, and low price [ 1 , 2 , 3 , 4 ]. Although pure PVC has excellent flame retardancy, its smoke-suppression property is rather weak.…”

Using introduction of MoO42− and Fe3+, Cu2+, or Zn2+ into amphiphilic polymers (DN) via an ion-exchange reaction, different transition metal complexes, as retardants and smoke suppressants, including (DN)Mo, Fe(DN)Mo, Cu(DN)Mo, and Zn(DN)Mo were synthesized. Combined with the results of X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR), it could be determined that ionic bonding of these ions with DN occurred. Subsequently, the influence of flame-retardant, smoke-suppression, and mechanical properties of (DN)Mo, Fe(DN)Mo, Cu(DN)Mo, and Zn(DN)Mo on polyvinyl Chloride (PVC) were tested. It was demonstrated that transition metal complexes of three metal elements, Fe(DN)Mo, Cu(DN)Mo, and Zn(DN)Mo, showed better flame retardancy, smoke suppression, and thermal stability as confirmed by microcalorimetry, limiting oxygen index (LOI), smoke density, and thermogravimetric analysis (TGA) tests, in which Cu(DN)Mo worked best due to the Lewis acid mechanism and reductive coupling mechanism. Scanning electron microscopy (SEM) showed that the addition of (DN)Mo, Fe(DN)Mo, Cu(DN)Mo, and Zn(DN)Mo promoted the formation of a dense carbon layer on the PVC surface during combustion, which could protect the interior PVC. The addition of these transition metal complexes hardly impaired the mechanical properties of PVC.
